@SpaceInMiBrain @SpoxSpace On Apollo, the LM was flown horizontally as you described with the astronauts on their backs and the windows facing away from the moon for most of the descent until final landing burn when the ship pitched round to vertical to land. Starship HLS will probably be similar.

Space In My Brain@SpaceInMiBrain·
This raises a question - with the seats and controls and windows oriented this way will the HLS be oriented vertically when flying in lunar obit or between lunar orbits, i.e. will the pilots face forward in the direction of travel, with the x-axis running through the ship's diameter and the pilot's chest. To do otherwise seems intuitively disorienting but I suppose people with the piloting skills of astronauts can manage it.

@ApexOutlander @Rainmaker1973 Okay I get Space X ambition and work. What was little bit strange to me is that going back to the moon looks so challenging today .. I get the reusability thing and new challenges, but ai thought that doing what we did in 1969 could be little bit easier now

@chinky365251453 @CuriosityonX Yes it can? Venus rotates slower on its own axis then it takes to make one full orbit of the Sun. A Venus day is shorter than a Venus year.

@TiceColin @NightSkyToday Because it's the first time humans have been past Earth orbit in 58 years? And this is a test flight not just for visiting the Moon but actual colonisation of the Moon and humans on Mars?

Night Sky Today@NightSkyToday·
🚨ATTENTION: The Artemis II astronauts will go through the most tense moment of the mission on April 6, 2026. This is the highlight of the entire mission. The Orion will pass between 6,400 and 9,600 kilometers above the lunar surface. But there's a detail that makes this moment even more intense: as it passes over the far side of the Moon, the spacecraft will lose communication with Earth for about 30 to 50 minutes, blocked by the Moon itself. "For the 45 minutes when we'll be closest to the lunar surface, we'll also be out of contact," said Victor Glover, the mission's pilot. "I'd love for the whole world to be cheering and praying for us to reestablish the signal." During that time, the astronauts will photograph and observe regions of the Moon's far side that have never been seen by human eyes. The crew will also attempt to capture new images of the so-called Earthrise, the planet emerging over the desolate lunar surface.

@hirohito4th @PenteanoO @F1BigData @thomasmaheronf1 With front wheel regen, enough battery can be recharged for acceleration up to top speed without LICO and super clipping so it doesn't matter if the battery runs out as the ICE is enough once up to speed. We don't need bigger batteries.

@DanRambaldi @PenteanoO @F1BigData @thomasmaheronf1 doesnt matter how much super clipping or lico or front wheel regen you have when you need more battery to actually make use of it. smaller cars have shown better racing, adding more battery + front generator just complicates packaging and weight. we ditched mgu h for a reason man

There's a growing awareness within the FIA that the 50/50 has been the wrong direction It's understood that, in the short-term, energy deployment limits are being looked at while, longer-term, a change in the ICE vs. electrical split 📰 @thomasmaheronf1

@DanRambaldi @PenteanoO @F1BigData @thomasmaheronf1 maximum power is 400kw ICE +350kw electric motor, when the battery is completely empty you physically cannot use 350kw from the motr so what are you left with? also i think you are confusing megajoules (energy unit) with extra power, its not, it just means you have more battery

@hirohito4th @PenteanoO @F1BigData @thomasmaheronf1 Overtake mode isn't an extra 350kW what are you on about. Overtake gives you an extra half a megajoule a lap of deployment so if all cars had the regen then they'd all have similar deployment, cars with overtake would just have a little more time with it.

@DanRambaldi @PenteanoO @F1BigData @thomasmaheronf1 mate which part of 50/50 split do you not understand if the battery cannot sustain that. even without super clipping, with the overtaking car at full boost, thats a whopping 350kw (500 hp ish) power difference. there is too much power going into the hybrid system

@ggrrrha @PeekPerfomance @F1BigData @thomasmaheronf1 Road relevance doesn't mean that manufacturers will use F1 parts in their cars. But F1 is the pinnacle of R&D for manufacturers and they want that R&D to translate into their road cars + the marketing relevance to their road cars is just as important to them.

@hirohito4th @PenteanoO @F1BigData @thomasmaheronf1 If the braking regen was increased then the super clipping and LICO wouldn't be needed. The ICE alone without super clipping has enough power even without the battery at the end of them. It's only because of the recharge they slow down

@SensSteadySteve @F1_driven I mean whilst I agree with the sentiment, the 'sudden' drop is actually really only the equivalent of 70 mph to 60 mph

I'm not going to lie, I was originally in the "clipping is bad" crowd but I can't help but feel there is an absolutely insane overreaction to the fact you can't just infinitely speed up along the whole straight. It's not really that big of a deal is it? Also has a simple fix so

@og_tadi @F1 @pirellisport Oh my god you people are so stupid. The only fair comparison is 2022 as 2025 was the 4th year of development of the old cars. In 2022, Verstappen's pole time was 1:29.304. The engine regs need some work but these cars are not slow.

So I did some analysis Last year, Verstappen clocked a 1:26.983 for pole. This year, Kimi did a 1:28.778. Considering the 3rd slowest car last year (Ocon at P18) was a 1:28.696, Kimi’s time would’ve landed him P19 at best on that grid. If you don't see anything wrong with that, I don’t know what to tell you. They need to do something fast because, honestly, wtf. 🙆‍♂️

@john_shako54250 @versatancore This is a stupid comparison because the 2025 cars had 4 seasons of development. The fair comparison is 2026 to 2022. Also these cars are still significantly faster than the 2014 cars

@versatancore This is from Google “Based on early 2026 pre-season data, the new F1 cars are significantly slower than 2025 models, with Melbourne qualifying times nearly 3.4 seconds slower than the previous year” Enjoy

Dean I appreciate your passion but we lifted and coasted back in the fearsome 80’s turbo days. And pretty much constantly in Sportscar racing at Le Mans and suchlike. Sometimes regulations determine total fuel use, but in any case you never want to carry excess fuel through a race, it’s guaranteed to slow you down. Through the eras the great champions had to manage and protect engines, tyres, brakes, clutch, gearbox, suspension, driveshafts, fuel load, and now battery charge. It’s all part of the challenge, the best simply have a greater capacity to manage those challenges whilst carrying winning speed.

@poszloooo @DreHarrison101 Management has been F1 for decades? Could change to Think twice before you push because you might use your tires, or end up having to refuel earlier than expected in the 90s/00s, or worries about reliability in the 80s. x.com/i/status/20169…
